Which rail passes would be best for us? Thanks!

None. As you only have one trip outside Osaka.

can cover train and bus rides for your trips
to USJ and back (train rides),
from Osaka to Kanazawa then to Toyama (#)
then back to Osaka (train rides),
from Kanazawa to Shirakawa-go
then back to Kanazawa (bus rides) and
from Osaka to Kyoto then back (train rides),
plus a JR train ride
for one way to or from Kansai-airport Station.

(#) The bus service between Shirakawa-go and Toyama Station
is currently suspended.

Thank you omotenashi!

So that means I need to buy tickets for Kyoto & Nara daytrip separately? Which options is best?

What do you mean bus to Shirakawa-go suspended? Will it still be on May?
